I have a problem with WC3, playing with joystick (CH Fighter Stick). The joystick calibrates correctly and works rather well, but the axes near the center are not very precise, and on the Y axis, when I pull slightly the stick down (just 1 cm or so, and not always), it tends to pull the ships' nose down, instead of up. If I pull it down more decidedly it doesn't happen, but it makes rather difficult to aim precisely at ships when they're coming towards me. I tried to widen the dead zones in the center, but the problem appears again just as the dead zone ends, in that case I just have to pull more the stick to make it happen.

Also, it seems to happen when there are more ships (it doesn't happen in the simulator).

I don't think it's a problem of the stick, because in the calibration screen such inverted values don't appear, neither I have problems with other games (also in DosBox). I tried all kinds of settings (timed, fcs, ch for joystick, different ram...), tried the WC3 joystick patches, but to no avail. Does anybody know which could be the cause?
